Obtain Provisioning Server's Address
17
(2) You need to update the settings
and restart the IP Phone after “Firmware Server Path” is set. If the
configured firmware server is found and a new code image is available, UC9xx IP Phone will attempt to
retrieve the new image files by downloading them into the
UC9xx’s SDRAM. During this stage, the
phones LEDs will blink more frequent until the checking/downloading process is finished. Upon
verification of checksum, the new code image will be saved into the Flash. If TFTP/HTTP/FTP/HTTPS
fails for any reason (e.g. TFTP/HTTP/FTP/HTTPS server is not responding, there are no code image files
available for upgrade, or checksum test fails, etc.), the phone will stop the TFTP/HTTP/FTP/HTTPS
process and simply boot using the existing code image in the flash.
(3) Firmware upgrade takes 3 to 8 minutes over Internet, or just 1 minute on a LAN. We recommend you
to upgrade the FW in a controlled LAN environment.
7. Obtain Provisioning Server's Address
Htek IP Phone supports to obtain the provisioning server address in below 3 ways:
Plug and Play (PnP) Server
DHCP Options
Phone Flash
The priority of obtaining the provisioning server address: PNP Server (SIP PnP MCAST) --> DHCP Option
128 or 150 or 66 --> Configuration in Flash.
1) The PNP Server feature is enable default.
2) Setting of "DHCP Option 128 or 150 or 66":
Webpage --> Management --> Auto Provision --> Allow DHCP Option (128 or 150 or 66) To Override
Server: No/Yes
If you set “Yes”, the Phone will obtain the provisioning server address from the DHCP Option (128). For
examples:
DHCP option 128 is
tftp://192.168.1.240/cfg
, the phone will get the configuration file from
192.168.1.240/cfg
through
TFTP protocol.
If the default setting is:
DHCP option 66 is
http://192.168.1.240/cfg
, the phone will get the configuration file from
192.168.1.240/cfg
through
HTTP
protocol.
Configuration in Flash.
If you set “No”, or don’t set DHCP option 128/66/150 in your DHCP server, the phone will obtain the
provisioning server address from the setting “Config Server Path”.
